  1. Let the first number = x
    Therefore, the second number = 27 – x
    According to the question,
    Product, = x(27 – x) = 182
    ⇒ 27x – x² = 182
    ⇒ x² – 27x + 182 = 0
    ⇒ x² – 13x – 14x + 182 = 0
    ⇒ x(x -13) – 14 (x -13) = 0
    ⇒ (x – 13) (x – 14) = 0
    ⇒ (x – 13) = 0 or (x – 14) = 0
    Either x = 13 or x = 14
    Hence, the two required numbers are 13 and 14
